Most people who book car shipping online are dealing with a broker, whether they know it or not. That is normal and legal. What matters is that every company in the chain is properly registered with the Federal Motor Carrier Safety Administration (FMCSA) and that each one is clear about its role.
Two roles, two kinds of registration
| Auto transport broker | Motor carrier | |
|---|---|---|
| What it does | Arranges transportation by an authorized carrier, for compensation | Physically hauls the vehicle |
| Owns or runs trucks | No (for the brokered load) | Yes |
| FMCSA registration | Broker operating authority with an MC docket number | USDOT number plus operating authority for for-hire interstate work |
| Financial requirement | $75,000 surety bond or trust fund | Its own liability and cargo coverage |
| Shows up on the BOL | Usually as the booking company | As the carrier that took possession |
What a broker is, and what it must have
Federal regulations (49 CFR 371.2) define a broker as a person who, for compensation, arranges or offers to arrange the transportation of property by an authorized motor carrier. In auto transport, an auto transport broker takes the order, posts it to carriers (often through a load board), and assigns it to a carrier that agrees to the price and timing.
Brokers are common because they solve a matching problem. A broker can offer one load to many carriers at once and place it with a truck already running that lane, which is hard for an individual shipper or a busy dealership to do alone.
To do that legally for interstate shipments, a broker needs:
- Operating authority. FMCSA says brokers register by filing the OP-1 application through its Unified Registration System, which assigns an MC number. The application fee is $300, and FMCSA estimates processing at about four to six weeks.
- A process agent filing. Form BOC-3 designates agents for legal process.
- Financial security. Under 49 CFR 387.307, a broker must have a surety bond or trust fund of $75,000 in effect, filed on Form BMC-84 (bond) or BMC-85 (trust fund). The bond or fund pays shippers or carriers if the broker fails to carry out its contracts.
The requirement is continuous, not a one-time filing. Under the same section, FMCSA will not register a broker until the full amount is in effect, and if claims paid out of the bond or fund push it below $75,000, the broker has seven business days to respond before FMCSA may suspend its authority.
Brokers also have to be transparent. Under 49 CFR 371.7, a broker may not represent its operations as a carrier's, and its advertising must show that it is a broker.
What a carrier is, and what it must have
A motor carrier is the company whose truck and driver actually move the vehicle. For-hire carriers hauling across state lines register with FMCSA and receive a USDOT number and operating authority. FMCSA's consumer advisory on auto transport says both brokers and carriers that operate interstate must be registered with the agency.
Carriers range from owner-operators running a single truck to companies with large fleets. Size matters less than registration, insurance and track record, all of which can be checked before the car is released.
The carrier is the party that signs the bill of lading, takes possession of the vehicle, and is responsible for it in transit. Its cargo insurance is what typically responds to a valid damage claim, so it is reasonable to ask for a certificate of insurance before pickup.
How to look up a company with FMCSA
Checking registration takes a few minutes and is worth doing before any shipment:
- Find the company's MC or USDOT number. FMCSA's advisory tells consumers to avoid auto transporters or brokers that do not prominently display their MC number on their website.
- Search the number in FMCSA's public licensing and insurance system (li-public.fmcsa.dot.gov), which the advisory points to.
- Confirm the entity type (broker, carrier, or both), that its authority is active, and that the legal name matches the company you are dealing with.
- For brokers, confirm a bond or trust fund is on file.
- At pickup, check that the carrier name and numbers on the truck and the BOL match a registered, authorized carrier.
Warning signs worth taking seriously:
- No MC or USDOT number anywhere on the website or quote
- A legal name in FMCSA records that does not match the company you are dealing with
- Pressure to pay a large deposit before any carrier is assigned
- A truck at pickup whose name and numbers do not match the dispatch details
FMCSA also accepts complaints about auto transporters and brokers through its National Consumer Complaint Database. Its advisory warns to be suspicious of any website where it is unclear whether the company is a broker or a transporter.
Where AutoTransportVehicle.com fits
AutoTransportVehicle.com is neither a broker nor a carrier. AutoTransportVehicle.com builds the quote widget that dealers, auctions and marketplaces embed on their pages, and it acts as a referral partner. When a shopper books through an AutoTransportVehicle.com widget, the shipment is arranged by AutoTransportVehicle.com's FMCSA-licensed fulfillment partner, which is the broker of record and assigns an authorized carrier. Prices shown in the widget are confirmed by that fulfillment partner.
For the shopper, the practical effect is a clear chain: the dealer or auction hosts the quote, the fulfillment partner arranges the shipment, and the carrier named on the bill of lading moves the car.
For the dealer or auction hosting the widget, that structure keeps the site out of the brokerage role while still giving shoppers an instant quote and a booking path. See for partners for how attribution works, or how auto transport works for the full shipment sequence.
Questions
Is it bad to book car shipping through a broker?
No. Brokers are a normal, regulated part of auto transport, and they give shippers access to many carriers at once. The important checks are that the broker has active FMCSA broker authority with a bond or trust fund on file, that it is clear about being a broker, and that the carrier it assigns is also registered and authorized.
What is the $75,000 broker bond for?
Federal rules require property brokers to keep $75,000 in financial security, through a surety bond or trust fund, as a condition of their authority. It is there to pay shippers or motor carriers if the broker fails to carry out its contracts. It is not cargo insurance for the vehicle; damage in transit is typically handled through the carrier.
What is the difference between an MC number and a USDOT number?
An MC docket number reflects operating authority, and FMCSA's auto transport advisory notes that both brokers and carriers receive one when they register for interstate work. Carriers, the companies that actually run trucks, also have a USDOT number. Either number lets you look the company up in FMCSA's public licensing records and confirm whether it is a broker, a carrier, or both.
Who is responsible if my car is damaged when a broker arranged the shipment?
The carrier that took possession of the car and signed the bill of lading is generally the party responsible for it in transit, and its cargo insurance typically responds to valid claims. The broker usually helps coordinate the claim. The exact process depends on federal rules and on your shipping agreement, so check its terms and keep your BOL and photos.
